Acetogenesis in the energy-starved deep biosphere – a paradox?

Frontiers in Microbiology, 2012
Under anoxic conditions in sediments, acetogens are often thought to be outcompeted by microorganisms performing energetically more favorable metabolic pathways, such as sulfate reduction or methanogenesis. Recent evidence from deep subseafloor sediments

Two‐Stage Anaerobic Digestion of Sugarcane Vinasse: A Bibliometric Analysis of Research Trends and Gaps

Environmental Quality Management, Volume 36, Issue 3, September 2026.
ABSTRACT Sugarcane vinasse, a by‐product of bioethanol production, poses a significant environmental challenge due to its high organic load and the large volumes generated. Anaerobic digestion (AD) has been widely explored as an alternative treatment, particularly in two‐stage configurations that can enhance methane recovery.
